Canopy in proper layout References Group No. 01, MAC (WP 0045 00)NOTEBoth the upper and lower portions of the orifice edge reinforcement may be spliced once per gore.REPAIRSplice a damaged orifice edge reinforcement as follows: 1. Place the canopy on the repair table with the damaged area up; smooth the area around the damaged orifice edge reinforcement. 2. If only the orifice edge reinforcement is damaged, cut a length of type III, nylon tape, long enough to extend 4-inches beyond each side of the damaged area. Sear the ends of the tape. Center the tape over the damaged area, and stitch according to the original construction and Table 2, WP 0012 00. 3. If damage to the orifice edge reinforcement extends into gore section(s), and requires replacement of the section(s), place the canopy on the repair table, smooth the damaged area, and pin the section(s) to the table. Be sure the radial and diagonal seams are straight. Cut the orifice edge reinforcement, close to the radial seams (or radial and diagonal seams) that border the damaged area. Cut a length of type III, nylon tape, long enough to extend 4-inches beyond each radial seam (or each radial seam and diagonal seam) involved. Sear the ends of the tape. Baste the 4-inch ends of the tape in place. Replace the gore section(s) adapting procedures in WP 0036 00. Use the tape as a guide for trimming the edge of the new section(s). Turn-under the raw edge ½-inch, and stitch the tape in place using the same sewing machine, thread, and stitch range as specified in step 2., above. END OF WORK PACKAGE
